The WRCS Hydrology and Hydraulics Software Suite WRCS has collected over two dozen software programs that represent a wide cross-section of  hydrologic and hydraulic modeling utilities developed for various applications in water resources engineering. These programs, and their User's Manuals and supplemental documentation files have been re-formatted on to one CD for easier installation and your convenience. Many of the programs have documentation in Adobe PDF format, which can be viewed with the Adobe Acrobat Reader, also included on the CD. This virtual library of hydrology and hydraulics computer software is available for only $45, and only from WRCS.  For ordering details, please see our Order Form Here is a list of the software packages on the CD, as well as a brief description of each. Click on any program title in the following list to go to the description of that program:  HYDROLOGY: ANNIE / HEC DSS / HSPF /  HYSEP / PeakFQ / SITES / SMADA / SWMM / SWSTAT / TR-20 / TR-55 HYDRAULICS: CAP / CHAMP / CHANLPRO / CHECK-RAS / FAN / Flo2DH / HY-8 Culverts / Quick-2 / RASPLOT / RUNUP / WHAFIS / WRAS / WSPRO HYDROLOGY PROGRAMS ANNIE ANNIE, Version 4.1, is a program designed to help users interactively store, retrieve, list, plot, check, and update spatial, parametric, and time-series data for hydrologic models and analyses. Data are stored in a direct access file called a Watershed Data Management (WDM) file. Many hydrologic and water-quality models and analyses developed by the U.S. Geological Survey (USGS) and the Environmental Protection Agency (EPA) currently use WDM files. HEC DSS The HEC Data Storage System (HEC-DSS or just DSS) stores data in a fashion convenient for inventory, retrieval, archiving and model use. The DSS was primarily designed for water resource applications.  The DSS can be interactively used with the following Corps of Engineers programs or program input and output data files: FFA, HEC-1, HEC-5, HEC-HMS, HEC-RAS, UNET. The user may interact with the data base through: a) Utilities that allow entry, editing, and display of information, b) Application programs that read from and write to the data base, c) Library routines that can be incorporated in any program to access data base information. The DSS provides a means for: 1) storing and maintaining data in a centralized location, 2) providing input to and storing output from application programs, 3) transferring data between application programs and, 4) displaying the data in graphs or tables. HSPF HSPF- Hydrological Simulation Program--Fortran simulates for extended periods of time the hydrologic, and associated water quality, processes on pervious and impervious land surfaces and in streams and well-mixed impoundments. HSPF uses continuous rainfall and other meteorologic records to compute streamflow hydrographs and pollutographs. HSPF simulates interception soil moisture, surface runoff, interflow, base flow, snowpack depth and water content, snowmelt, evapotranspiration, ground-water recharge, dissolved oxygen, biochemical oxygen demand (BOD), temperature, pesticides, conservatives, fecal coliforms, sediment detachment and transport, sediment routing by particle size, channel routing, reservoir routing, constituent routing, pH, ammonia, nitrite-nitrate, organic nitrogen, orthophosphate, organic phosphorus, phytoplankton, and zooplankton.  HYSEP HYSEP - Hydrograph separation program performs hydrograph separation, estimating the ground-water, or base flow, component of streamflow. The program provides an automated and consistent method for estimating base flow. Any of the three hydrograph-separation techniques of Pettyjohn and Henning (1979) can be used: fixed interval, sliding interval, or local minimum. PeakFQ PEAKFQ - (Version 5.2) Flood-frequency analysis based on Bulletin 17B performs flood-frequency analysis based on the guidelines delineated in Bulletin 17B, published by the Interagency Advisory Committee on Water Data in 1982. The program is interactive and contains the code from the WATSTORE program J407. SITES 2005 SITES 2005  - The SITES software is a descendent of the DAMS2 program. DAMS2 was a full-featured rainfall-runoff routing program developed for watershed dam design and analysis. In developing the SITES software, DAMS2 was recoded and the auxiliary (emergency) spillway analysis portion of the program was rewritten and expanded to include new technology for spillway performance evaluation.  SMADA SMADA - Stormwater Management and Design Aid - This software is a complete hydrology package included as a number of separate executable files. These programs work together to allow hydrograph generation, pond routing, storm sewer design, statistical distribution and regression analysis, pollutant loading modeling, matrix calculation, and others. These programs are useful in both classroom and professional applications. Extensive on-line documentation is available for all programs.  SWMM SWMM Storm Water Management Model versions 5.0 and 4.4 - This Rainfall Runoff Model was developed by the US Environmental Protection Agency, Oregon State University and Camp, Dresser & McKee, Inc. It is a large, complex model capable of modeling the movement of precipitation and pollutants from the ground surface through pipe and channel networks, storage treatment units, and finally to receiving waters. Both single event and continuous simulation can be performed on catchments having storm sewers and natural drainage, for prediction of flows, stages and pollutant concentrations. SWSTAT SWSTAT,  Surface-Water STATistics - (Version 4.1) contains a number of options for statistically analyzing time-series data. The time-series data are read from a Watershed Data Management (WDM) file. The computed statistics and (or) time series can be written back to the WDM file or to a text file. The statistics options include: Basic, Compare, Duration, Frquency, Hydrograph, N-Day and Trend. TR-20 TR-20, Technical Release No. 20: Computer Program for Project Formulation Hydrology (TR-20) is a physically based watershed scale runoff event model. It computes direct runoff and develops hydrographs resulting from any synthetic or natural rainstorm. Developed hydrographs are routed through stream and valley reaches as well as through reservoirs. Hydrographs are combined from tributaries with those on the main stream stem. Branching flow (diversions), and baseflow can also be accommodated.  TR-55 TR-55, Urban Hydrology for Small Watersheds - Technical Release 55 (TR-55) presents simplified procedures to calculate storm runoff volume, peak rate of discharge, hydrographs, and storage volumes required for floodwater reservoirs. These procedures are applicable in small watersheds, especially urbanizing watersheds, in the United States. HYDRAULICS PROGRAMS CAP Culvert Analysis Program CAP follows USGS standardized procedures for computing flow through culverts. It can be used to develop stage-discharge relationships for culverts and to determine discharge through culverts from high water marks. It will compute flows for rectangular, circular, pipe arch, elliptical, and other nonstandard shaped culverts. CHAMP Coastal Hazard Analysis Modeling Program, Version 2 CHAMP is a program for performing coastal hazard assessments of fine-scale wave phenomena associated with hurricane storm surges or northeaster flooding effects. These methodologies include storm-induced erosion treatments, wave height analyses, and wave runup analyses. CHAMP allows the user to enter data, perform coastal engineering analyses, view and tabulate results, and chart summary information for each representative transect along a coastline within a user-friendly graphical interface.  CHANLPRO CHANLPRO, Version  2, numerical modeling system addresses three areas pertinent to the design of channel protection. First the program contains the U.S. Army Corps of Engineers (USACE) riprap design guidance for placement in the dry for channels subjected to velocity forces in low turbulent flow. Second the program provides guidance for the design of gabion mattresses for the same flow conditions as the riprap design guidance. Third the program provides guidance for estimating scour depth in erodible channels. CHECK-RAS CHECK-RAS, Version 1.4, is a program designed to verify the validity of an assortment of parameters found in the HEC-RAS hydraulic modeling program.  FAN FAN, produced by The Federal Emergency Management Agency (FEMA), aids in the evaluation and mapping of flood hazards on alluvial fans.  FST2DH FST2DH, Version 3.22, (Formerly Flo2DH) is a two-dimensional finite element surface water computer program that can compute the direction of flow and water surface elevation in a horizontal plane. Flo2DH has the ability to model hydraulic structures commonly used by hydraulic engineers.  HY-8 Culverts HY8 Culvert Analysis, Version 7.0, This culvert analysis program automates the design methods described in the Federal Highways Administration (FHWA) publications HDS-5, "Hydraulic Design of Highway Culverts," HEC-14, "Hydraulic Design of Energy Dissipators for Culverts and Channels," and HEC-19, "Hydrology."  Quick-2 Quick-2, Version 2.0, is the latest version of a hydraulic analysis program used to compute water-surface elevations in open channels of all types.  RASPLOT RASPLOT, Version 2.5, produces plots from Corps of Engineers HEC-RAS program output files for use in FEMA Flood Insurance Studies. The program replaces FEMA's FISPLOT program.  RUNUP RUNUP, Version 2.0, is a DOS-based program for wave runup computation. This program uses stillwater elevation, shore profile and roughness, and incident wave condition input information to compute a wave runup elevation that is consistent with the most detailed guidance currently available. WHAFIS Wave Height Analysis for Flood Insurance Studies, Version 3.0, is a DOS-based program that uses representative transects to compute wave crest elevations in a given study area. Transects are selected considering major topographic, vegetative, and cultural features. WHAFIS uses this and other input information to compute an appropriate depth-limited wave height at the seaward end of each transect. WRAS WRAS is a conversion program developed by the Natural Resources Conservation Service (NRCS) that takes existing WSP2 data sets and converts them in HEC-RAS format for import into HEC-RAS. WSPRO HY7 WSPRO (2001) is a water surface profile computation model that can be used to analyze one-dimensional, gradually-varied, steady flow in open channels. WSPRO can also be used to analyze flow through bridges and culverts, embankment overflow, and scour at bridges.
